Lignin, one of the most abundant organic polymers on Earth, is an integral part of the cell walls of almost all vascular plants. But what is another name for lignin, and why is this complex substance so vital for plant structure and strength?

Cellulose is the most abundant organic polymer on Earth, making up a significant portion of all plant matter, including wood. However, despite being a carbohydrate, wood does not provide digestible fats, carbs, or proteins for humans, as we lack the necessary enzymes to break it down.

Did you know plants contain between 0.005 and 5% calcium by dry weight, making it a critical macronutrient for growth? In response to the question, "Does wood contain calcium?", the answer is a definitive yes, as trees incorporate this mineral into their woody tissues for structural stability and physiological function.

On a dry-weight basis, a significant portion of wood—ranging from 65-75%—consists of carbohydrates. These are not the simple sugars we find in food, but complex polymers that serve as the primary building blocks of the plant's cell walls, providing strength and structure.

According to a study in the Proceedings of the National Academy of Sciences, wood does contain small quantities of a cell-wall structural protein. This surprising biological fact, however, does not mean that wood is a viable dietary protein source, leading to a deeper look into the question: does wood have protein in it?

Over 3.6 million workers in the European Union were exposed to wood dust between 2000 and 2003, highlighting its prevalence, yet many misunderstand its core components. The question, 'Is cellulose like sawdust?' stems from the common origin of these two materials, but a closer examination reveals they are far from identical. Sawdust is an impure byproduct, while purified cellulose is a highly versatile and distinct organic compound used across numerous industries.
